If the scenery was immovable, it was very rich and secrets of theoretical mechanism often produced surprising and fairy-like effects.

Quantum evolution is an attempt to provide a theoretical mechanism which would skew these random mutations in favor of some outcome beneficial to the cell.

Another theoretical mechanism of action is based on the structural similarities of antineoplaston A10 to other experimental anticancer drugs such as carmustine and 5-cinnamoyl-6-aminouracil.

His work has made great strides in the understanding of viruses and their replication, as well as theoretical mechanisms in the origin of life.

Adaptive mutation is a theoretical evolutionary mechanism.

Despite the complexity of the underlying theoretical mechanism, the practical use of an EDD is straightforward.

Other scientists disputed the factual basis of the theoretical mechanism assumed by this approach.

The theoretical mechanism is quite simple:

Trait ascription bias, regardless of the theoretical mechanisms underpinning it, intuitively plays a role in various social phenomenon observed in the wild.

Despite careful observation of developing embryos, epigenesis suffered from a lack of a theoretical mechanism of generation.
